JOHN HANCOCK, OF ALTON, ILLINOIS.

FLUlD PRESSURE REGULATOR.

LLPECIFIOATION forming part of Letters Patent No. 744,964, datedNovember 24, 1903.

Application filed March 9, 1903.

To all whom, it may concern:

Beitknown thatLJOHNHANOOCK, acitizen of the United States, residing atAlton, in the county of Madison and State of Illinois, have inventedcertain new and useful Improvements in Fluid-Pressure Regulators; and Ido hereby declare that the following is a full, clear, andexactdescription of the same, reference being had to the annexeddrawings, making a part of this specification, and to the letters ofreference marked thereon.

The present invention has for its object to provide a simple andeffective means for controlling the pressure of the gas in gas-burnersor gas-stoves, and which is especially applicable to the gas-burnersemploying the usual mantles, which are liable to breakage caused by thepressure of gas when lighting the same.

The invention therefore consists in a fluidpressure regulatorconstructed substantially as shown in the drawings and hereinafterdescribed and claimed.

Figure 1 of the drawings is a sectional view showing the application ofmy invention to the tube of a gas-burner; Fig. 2, a perspeotive view ofthe device detached from the tube.

In the accompanying drawings, A represents the tube of a gas-burner,which may be of any of the usual forms and has the shoulder 0t andscrew-threaded extension Z) to connect it with the burner, said tube, asherein shown, being one of many forms to which my invention isapplicable, the screw-threaded extension having connected to its upperend the perforated diaphragm B, through which the gas or other fluidpasses to the burner.

Within the tube A or extension thereof is located a perforated plate 0,which is preferably concavo-convex and of circular form to correspond insize to the interior circumference of the tube or extension and islocated in near proximity to the perforated diaphragm B. The perforatedplate 0 is connected to the upper end of a guide-rod D, which is ofsufficient length to project below .the end of the tube, so as to enablethe fingers to grasp the end of the rod in withdrawing or inserting thesame in the tube, and, if preferred, the rod may be pointed at. its end,

as shown at c in Fig. 2 of the drawings, to facilitate placing thereonthe disks E. These disks are of felt or other similar fibrous materialand may be of any suitable thickness, and one or more disks may be used,as found desirable, said disks being of a circumference corresponding tothat of the interior of the tube or extension thereof. The concavity ofthe perforated plate 0 prevents the upper face or surface of the disk Efrom coming in contact therewith and closing the perforations, while therod D enables the disks to be removed when filled with dirt, dust, orother sediment and replaced by new ones. The disks may also be adjustedalong the rod to increase or diminish the space between the disk and theperforated plate, the disks fitting sufficiently tight upon the rod toresist the pressure of the inflowing gas. This is not absolutelyessential, however, and it is preferred that the disks be in positionwith relation to the perforated plate as indicated in Fig.1 of thedrawings; but should such adjustment of the disks be deemed necessaryprovision is made therefor. The perforated plate C and the fibrous disksE control the pressure of the inflowing gas, and where a mantle is usedwith a gasburner it prevents injury thereto by the pressure of the gaswhen lighting it. The fibrous disks E check the pressure of the gas andallow it to feed through the perforations in the plate 0 and through theperforations in the diaphragm B to the burner, thereby regulating thepressure of the gas whether strong or weak and rendering it uniform inits supply to the burner.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. In a fluid-pressure regulator, a suitable tube through which the gaspasses to the burner, a perforated plate located therein and a rodconnecting therewith, said plate and rod removable from the tube, and afibrous disk upon the rod below the perforated plate, substantially asand for the purpose described.

2. In a fluid-pressure regulator, a suitable tube through which the gaspasses to the burner, a perforated diaphragm upon the upper end of thetube, a perforated disk and rod connected thereto and removable from thetube, and a disk of fibrous material adjust- I therewith, and a disk offibrous materialsup- 1o ably and removably supported upon the rod,ported upon the rod, substantially as and for substantially as and forthe purpose specified. the purpose set forth.
